Part# 32-853-68-S for Kohler Carburetor KT715 KT725 7000

What It Is

Part# 32-853-68-S is a complete carburetor assembly designed for Kohler 7000 Series KT715 and KT725 engines. It replaces the factory carburetor on residential zero-turn mowers, lawn tractors, and commercial stand-on mowers equipped with these engines.

Fitment & Compatibility

• Engine models: Kohler KT715, KT725 (7000 Series). Verify your engine model number—it’s stamped on the valve cover or blower housing.
• OEM reference: This is an aftermarket replacement for OEM Kohler part #32-853-68-S. It matches the original dimensions and fuel line connections.
• Deck size: Not deck-dependent—compatibility is strictly engine-based. Works on any mower with the specified Kohler engines (e.g., Gravely, Hustler, Cub Cadet, Bad Boy).
• Measurements: Check that your fuel line inner diameter (typically 1/4” or 5/16”) matches the carburetor inlet. Also verify the choke linkage style—some KT7 variants use a remote choke cable; this carb includes a fixed choke plate.
• Gaskets: Ensure your air filter base and intake manifold gaskets are in good condition—reuse or replace separately if needed.

Key Things to Know

• Quality variance: Aftermarket carburetors may have slightly different jetting than OEM. If your mower runs rich or lean, you may need to clean or swap the main jet.
• Installation difficulty: Moderate. Expect 30–60 minutes. You’ll need basic hand tools, a small flathead screwdriver for the float bowl, and possibly a torque wrench for the mounting bolts (8–10 ft-lbs).
• Common gotcha: The float bowl is often over-tightened from the factory. Use a light hand to avoid stripping the bowl nut or cracking the plastic housing.
• No adjustment needed: This is a fixed-jet carburetor—no idle mixture screw. If idle speed is off, adjust the throttle stop screw on the linkage.

Should You Buy It

If your Kohler KT715 or KT725 engine is surging, hard-starting, or leaking fuel, this $35 aftermarket carburetor is a solid, low-cost fix. It’s best for DIY owners who want a drop-in replacement without rebuilding the original. Skip it if you prefer OEM parts for warranty or commercial use—those run $80–120.
